From the perspective of nutritional science, glutamine, like arginine, is not an essential amino acid. Nevertheless, glutamine is the most abundant amino acid in the body. Glutamine plays major roles in accelerating muscle metabolism, in preserving muscle, in promoting wound healing and in cell proliferation. It also serves as the nutritional source for gastrointestinal cells and as the major e...

genetic programming (gp) is one of the computer algorithms in the family of evolutionary-computational methods, which have been shown to provide reliable solutions to complex optimization problems. the genetic programming under discussion in this work relies on tree-like building blocks, and thus supports process modeling with varying structure. in this paper the systems containing amino acids ...

background & aim: clematis is an ornamental and medicinal plant that is primarily planted as an ornamental plant. clematis orientalis is native to asia and central europe, used as an antiseptic and refrigerant. the propagation of clematis is very important. in this study, the effects of plant growth regulators on rooting and growth of the plants in vitro culture were examined. experimental:...

Two experiments were conducted to determine the effects of essential amino acid deficiencies on several immunological variables in male broiler chickens. Essential amino acids were classified into five groups as follows: S-containing amino acids (SAA; methionine + cysteine), aromatic amino acids (AAA; phenylalanine + tyrosine), branched-chain amino acids (BCAA; isoleucine + leucine + valine), a...

L-phenylalanine (Phe), an essential amino acid, is necessary for the synthesis of proteins such as catecholamine and melanin, also precursor acid L-tyrosine (Tyr). In this paper, optimized structures Phe, were calculated by using semi-empirical models AM1, PM3 MNDO; Density Functional (DFT) at B3LYP Hartreefock methods (HF) with 6-311++G (d,p) level. The energies geometric parameters Kaempferol...

the interaction of p-sulphonatocalix [6] arene towards l-arginine and l-lysine has been studied inacidic aqueous solution (p1-1 2) using uv-vis spectrophotometric titration technique. the psulphonatocalix[6] arene was found to be able to form 1:1 complexe with amino acids in water.the values of the association constant were determined at different temperatures to evaluate thethermodynamic funct...

objective: the objective of this study was to investigate the pathological alterations of methionine for chicken embryo.in recent years, amino acids are used in veterinary medicine for many purposes. they injected into hatching eggs to increase chick body weight and performance at hatch, but the adverse effects of amino acids have always been a major concern. there is scant information availabl...

1. Free amino acids were determined in the plasma and in the muscle tissue of 14 patients with chronic uraemia; eight were not on dialysis and six were having regular peritoneal dialysis. The concentration of each amino acid in muscle water was calculated with the chloride method. 2. In both groups of patients there were low intracellular concentrations of threonine, valine, tyrosine and carnos...

It is well known that dietary protein affects the growth performance and carcass composition of poultry. Over the last several decades, numerous studies have been carried out to investigate to optimize the level of dietary protein since the protein is an important and expensive constituent in poultry feed. It is generally accepted that dietary protein should represent a balance of amino acids s...

The objective of the study was to determine the crude protein content and amino acid composition in bee-collected pollen from selected areas of Poland, South Korea and China. A total of 27 samples of pollen were examined after collection by bees. The dry substance, crude protein and amino acids were investigated in the study material. Amino acids were determined by ion exchange chromatography u...
